Need Icing Recipe For Roses

I took the Wilton I class last summer and learned how to make roses - hopefully it will come back to me when I start to make the bridal shower cake for this weekend Anyway, what I really remember is not liking the icing recipe they had us use. I was hoping someone had another yummy icing that worked well for making roses.Also, how far ahead of time can I make the roses? I've got two kids under 3, so I have to plan my cakes in stages Thanks in advance!!!Tabby
